FILTER.

SPECIFICATION forming part of Letters Patent N o. 661,602, dated November 13, 1900.

Application filed August 6, 1900. Serial No. 26.023. (No model.)

To (LZZ whom, it may concern:

Be it known that I, ARTHUR F. GARESCH, a citizen of the United States, residing at the ett-y of St. Louis, State of Missouri, have invent-ed a cert-ain new and useful Improvement in Filters, of which the following is a full, clear, andexact description, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, forming part of this specification, in Which- Figure 1 is a vertical sectional view of my improved filter. Fig. 2 is a horizontal sectional View on line 2 2, Fig. l; and Fig. 3 is a vertical sectional view on line 3 3, Fig. 1, the plunger being omitted.

This invention relates to a new and useful improvement in filters, and particularly to the devices hereinafter described for cleaning the filtering material, the object being to enable the filtering material being cleansed from the exterior without dismantling the filter, the dirty water resulting from the cleaning operation being confined in a chamber,

from which it may be racked or drawn of by.

suitable devices.

With this object in view theinvent-ion consists in the construction, arrangement, and combination of the several parts, all as wiil be hereinafter described and afterward pointed out in the claims.

In the drawings, A indicates a receptacle for receiving the filtered water, said receptacle being preferably provided with a spigot a.

B indicates a receptacle for containing the wat-er to be filtered, said receptacle preferably carrying a panel C in its bottom, forming the filtering material. This construction obtains where a gravity-filter is employed;

^ but it is obvious that in pressure-filters the its carried parts may be rotated as desired. go

The lower end of rod E carries a disk F,

sulting from the cleaning operation being confined below the disk F and not permitted to mingle with the water above said disk to be filtered. When the filtering-surface is cleansed, a spigot b may be opened to draw off the dirty water beneath the disk, the cleaner water above owing around the disk on all sides as the dirty water is removed.

As shown in Fig. l, a plunger H may be arranged in the tube E, the lower end of said tube opening into the compartment below the disk F, the cleats forming the waysf and the back'of the brush being cut away opposite the tiibe E to give access of the dirty water to the tube. When the plunger H is reciprocated, t-he dirty water is pumped from under disk F and elevated in the hollow tube until it reaches a spout e, under which spout a bucket or other receptacle may be placed. By thus providing a centrally-located exit for the dirty water the water above the disk F will flow around and under the edges of said disk uniformly on all sides, so that all of the dirty water will be removed from above the filter-surface.

As it is not necessary that the cleansing apparatus should remain in an operative position at all times, achain lis provided,whereby when the cleansing apparatus is elevated in the receptacle, as shown by dotted lines in Fig. l, said chain by being attached to a hook arranged at some suitable point will hold the cleansing apparatus in its elevated position. 93

I am aware that minor changes in the ar- `rangement, construction, and combination of the several parts of my device can be made and substituted forthose herein shown and described Without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1,. In a filter, the combination with ay suitable receptacle and filtering material, of a device designed to coperate with the surface of the filtering material to cleanse the latter, a disk for conning the dirty water in a space adjacent to said filtering material, means for operatingthe cleansing apparatus, and means for drawing the dirty water resulting from the cleansing operation, from the filter; substantially as described.

2. In a filter, the combination with a suitable receptacle and filtering material', of a rod, a disk carried by said rod, said disk being of slightly-smaller diameter than the receptacle, anda brush mounted upon-saidd-isk for cleansing the surface of the filtering material; substantially as described.

3. In a filter, the combination with a receptacle and filtering material, of a hollow rod, a disk mounted upon the endk of said rod', a brush carried by said disk for cleansing-the surface of the filtering material, and a` plungerlocated inthe hollow rod for drawing the Water resultingfrom the cleansing operation, through the hollow-rod; substantially as described.

4. In a filter, the combination with a suitable receptacle and ltering material, of a device designed to coperate with the surface .of the filtering material to cleanse the latter, a disk for confining the dirty Water in a space adjacent to said filtering material, means for operating the cleansing apparatus, and means for holding said disk and said cleansing device out of operative relation to the surface of said material; substantially as described.

5. In a device for cleaning the surface of filtering material, the combination with a hollow rod, of a plunger in said rod, a disk car- `ried by said rod, Ways provided on said disk for the reception of the brush, anda brush, isa-id brush and ways being cut away opposite I'the hollowrod te give access to the open end thereof; substantially as described.

Inv testimony .whereof I hereunto affix my signature, in the presence of two witnesses, this 2d day of'Afugust, 1900.
